Hi there fellow Monks,

I have a bit of an odd problem with uncompressing a .gz file. If I uncompress an Office file that has been gzipped then the Office file becomes corrupt. This is true with the old office format (doc,xls) and the new format (docx,xlsx).

If however I uncompress any other file (eg: avi,txt,bmp) that has been gzipped then there are no problems. I've tried using Archive::Extract and IO::Uncompress::Gunzip and I get the same results with both.

Here is the code I'm using for Archive::Extract: 
use strict;
use warnings;
use Archive::Extract;
my $file = "Testing.xls.gz";

my $ae  = Archive::Extract->new(archive => $file);
unless(my $ok = $ae->extract){
    print "There was an error: $ae->error";    
}

Here is the code I'm using for IO::Uncompress::Gunzip: 
use strict;
use warnings;
use IO::Uncompress::Gunzip qw(gunzip $GunzipError);
my $file = "Testing.xls.gz";
my $out = "Testing.xls";

my $status = gunzip $file => $out or die "gunzip failed: $GunzipError\
+n";

Any help with this will be greatly appreciated.
